Square Root in R (5 Examples) | Apply sqrt Function in R Studio

In this tutorial, I’m going to show you how to calculate the square root in R. The tutorial is mainly based on the sqrt function:

Basic R Syntax:

sqrt(x)

sqrt(x)

Definition:

The sqrt R function computes the square root of a numeric data object.

In the following article, I’ll show you five examples for the application of sqrt in the R programming language. Examples 1 and 2 illustrate the basic application of sqrt and Examples 3, 4, and 5 show some typical warnings and errors that can occur when sqrt is applied in a wrong way.

So without further ado, let’s get started!

Example 1: Calculate Square Root of Numeric Value in R

In the first example, I’m going to apply the sqrt function to a single numeric value. Let’s first create such a numeric data object:

x1 <-16# Data object containing numeric value

x1 <- 16 # Data object containing numeric value

The exemplifying data object contains the value 16. Now, we can apply the sqrt R function to this numeric data object:

Video Tutorial: Manual Computation of the Square Root

In this R tutorial, we learned a lot about the programming routines that we can apply when calculating a square root. However, we have not learned much about the mathematical background itself. In case you want to learn more about the mathematics behind the square root, I can recommend the following video of the tecmath YouTube channel. The video explains some simple math tricks for the manual computation of the square root.
